2. Parabolic reflector - Wikipedia

   en.wikipedia.org/wiki/Parabolic_reflector

   A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves. Its shape is part of a circular paraboloid , that is, the surface generated by a parabola revolving around its axis.

3. Concentrated solar power - Wikipedia

   en.wikipedia.org/wiki/Concentrated_solar_power

   A parabolic trough consists of a linear parabolic reflector that concentrates light onto a receiver positioned along the reflector's focal line. The receiver is a tube positioned at the longitudinal focal line of the parabolic mirror and filled with a working fluid.

4. Parabolic aluminized reflector - Wikipedia

   en.wikipedia.org/wiki/Parabolic_aluminized_reflector

   A parabolic aluminized reflector lamp (PAR lamp or simply PAR) is a type of electric lamp that is widely used in commercial, residential, and transportation illumination. It produces a highly directional beam. Usage includes theatrical lighting, locomotive headlamps, aircraft landing lights, and residential and commercial recessed lights ("cans ...

5. Parabolic trough - Wikipedia

   en.wikipedia.org/wiki/Parabolic_trough

   A parabolic trough is made of a number of solar collector modules (SCM) fixed together to move as one solar collector assembly (SCA). A SCM could have a length up to 15 metres (49 ft 3 in) or more. About a dozen or more of SCM make each SCA up to 200 metres (656 ft 2 in) length. Each SCA is an independently-tracking parabolic trough. [9]

6. Remote Skylights - Wikipedia

   en.wikipedia.org/wiki/Remote_Skylights

   Remote Skylights are optical systems capable of providing natural light to unlit locations. An arrangement of parabolic reflectors and optical fiber cables, transport natural sunlight to areas that would otherwise be dark or be lit artificially. Remote skylights are composed chiefly of a solar collection dish, a "heliotube" and a distribution ...

7. Solar mirror - Wikipedia

   en.wikipedia.org/wiki/Solar_mirror

   Metal reflectors offer some advantages over glass reflectors, as they are lightweight and stronger than glass and relatively inexpensive. The ability to retain parabolic shape in reflectors is another advantage, and normally the subframe requirements are reduced by more than 300%. The top surface reflection coating allows for better efficiency.
